GopherCon Europe 2023: Maciej Rzasa - API Optimization Tale: Monitor, Fix and Deploy

About the talk: I saw a green build on a Friday afternoon. I knew should push it to production before the weekend. My gut told me it was a trap. I had already stayed late to revert a broken deploy. I knew the risk.

In the middle of service extraction from a monolithic platform, we were had to replace a slow REST API with GraphQL and optimize its usage. This let us, notice patterns of a predictable GraphQL consumer.

Deploy on Friday? Testing on production? Big refactoring in a safe way? But why and how? I’ll tell you a tale of incremental changes, monitoring, and good old tricks in a new setting. Hope, despair, and broken production included ;-).
